What is typically included during a performance interval?

During a performance interval, which is often referred to as an intermission, the primary purpose is to provide a break for the audience. This time allows the audience to stretch, use facilities, and refresh themselves before the performance continues. It serves as a crucial moment for attendees to process what they have just watched, discuss it with fellow viewers, and prepare for the second act or the remainder of the show.

While other activities can occur during this time, such as set changes and sound checks, these functions are not typically the focus from the audience's perspective. Audience feedback happens mainly after the performance is complete, and actor wardrobe changes usually occur backstage where the audience is not privy to those details. Therefore, the interval primarily facilitates a break for the audience, making it the most appropriate answer.
